(Embodiment 1)
Although not shown, the ventilation opening according to the present embodiment is attached to the indoor side of a ventilation path that penetrates a wall separating the outdoor and the indoor. Outdoor hoods are often provided outside the room to prevent rainwater from entering. Ventilation of a building is performed by exhaust air from a ventilation fan provided in a toilet, hallway, kitchen, or the like, and supply air that flows in from the ventilation port or the like along with the exhaust air. That is, when the exhaust fan is operated and forced exhaust is performed, a pressure difference is generated between the room and the outside, and the room becomes a negative pressure. In order to perform effective ventilation, a ventilation port as an intake port for supplying air is used. In addition, the opening of the ventilation port can be temporarily closed in order to prevent water from entering when there is concern about outside noise, or when snow, rain, or wind such as a snowstorm or typhoon is strong.
